Kansas is best known for '70s-era recordings with Steve Walsh and Kerry Livgren, including 'Carry On Wayward Son,' 'Dust in the Wind' and 'Point of Know Return,' among others. When the two became at odds, Kansas found some success in the early '80s with John Elefante ('Play The Game Tonight') before Walsh's eventual return in 1985. He still leads the band, which regularly tours with fellow original members Phil Ehart and Rich Williams.

Meanwhile, Kiss' brand has, in some ways, become bigger than its music -- as founding members Gene Simmons and Paul Stanley led the band's touring, recording and yes, merchandising activities into a fourth decade. They lost members along the way too (notably fellow founders Peter Criss and Ace Frehley), but that hasn't slowed them down one bit: Kiss released its 20th studio effort in 2012, and entered the Rock and Roll Hall of Fame in 2014.
